Chiquita Sea Lake

Mar Chiquita is a vast saline lake in a closed basin of the central Argentine plains. The Dulce enters through extensive northern wetlands, while the Primero and Segundo rivers reach the basin from the south. With no outlet to the sea, the lake changes in extent and salinity as inflow and evaporation vary. Sanavirón communities inhabited the lower Dulce and the country around the lake before Spanish conquest.
